Torque and Forces Quiz

What is the primary equation used to calculate torque in this problem?

• Force divided by distance

• Force times distance

• Force plus lever arm

• Force times lever arm times sine of angle

Why does force number one produce zero torque?

• Because it is not perpendicular to the door

• Because it is applied at the axis of rotation

• Because it is applied at a 45-degree angle

• Because it is too weak

What is the torque produced by force number two?

• 20 Newton meter

• 15 Newton meter

• 5 Newton meter

• 10 Newton meter

In which direction does a positive torque cause an object to rotate?

• Downward

• Upward

• Counterclockwise

• Clockwise

What is the magnitude of the torque produced by force number three?

• 42 Newton meter

• 36 Newton meter

• 30 Newton meter

• 24 Newton meter

What is the direction of the torque vector for a negative torque?

• Out of the board

• Into the board

• Perpendicular to the board

• Parallel to the board

What angle is used to calculate the torque for force number four?

• 90 degrees

• 120 degrees

• 150 degrees

• 180 degrees

Why does force number five produce zero torque?

• Because it is not perpendicular to the door

• Because it is parallel to the radial vector

• Because it is applied at the axis of rotation

• Because it is too weak
